To all whom it may concern:

Be it known that I, EDWARD N. TRUMP, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Lixiviating Apparatus, of which the following, taken in connection with the accompanying drawing, is a full, clear, and exact description.

My invention relates to improvements in lixiviating apparatus, and has for its object the production of a device which is simple in construction, continuous in operation, highly eilicient in use, and requires a minimum amount of attention; and to this end, the inventionconsists in the combination, construction, and arrangement of the component parts of a lixiviating apparatus, all as hereinafter fully described and pointed out in the claims. I

In describing this invention, reference is had to the accompanying drawing, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a longitudinal vertical section, partly in elevation, of-my improved lixiviatmg apparatus. Figs. 2, 3 and 4 are transverse vertical sections, taken, respectively, on lines 22, 3 3, and 4 4, Fig. 1. Figs. 5 and 6 are transverse verticalsections, lookingin opposite directions, taken on line 5--6, Fig. 1; and Fig. 7 is a longitudinal vertical section, partly in elevation, of a modified construction of my improved lixiviating apparatus.

As usually constructed, a lixiviating apparatus consists of a number of fixed chambers or'receptacles, conduits or pipes for 0611- necting the chambers or receptacles'in different series or batteries, and supply conduits or pipes for conducting the soluble material and the dissolvent liquid, respectively, to the first and last chambers or receptacles of the various series of batteries. A lixiviating apparatus of this construction requires con.- siderable attention,..and the lixiviation eiiected thereby is more or less Lin-uniform, owing to the variation in the connection of the dil ferent chambers or receptacles. My present invention is radically different from such apparatus, since the dissolvent liquid and the soluble material are continuously fed therethrough in opposite directions without liability of variation in the proces or the necessity of rearrangement of the component parts of the apparatus.

partments am anged within. the inclosing shell, and B G inlet-conduits or pi es for feeding the soluble material and the issolvent liquid. The shell A preferably consists of a revoluble c linder which is usually sup ported in an inc ined lane, and the compartments 0, a are generally inclosed between the lower portions of the convolutions of a spirally arranged conveyer-blade a which is fixed to the inner face of said shell and changes the pos tion of said compartments as the'shell A is re, olved.

The inlet-conduit or pipe'B for thesoluble material preferably discharges into thelower end of the shell Aland the material discharged from said conduit or pipe is fed lengthwise of the shell A by thle conveyerblade a. Said inlet-conduit or pipe is usually formed with an enlarged fiarii ig up er extremity, and is mounted upon a uita le support. As here illustrated, the s pport for the conduit or pipe B consists o f a stationary chamber D which isprovided ,with an outlet-pi e or conduit d and communicates with the s iell A for receiving the solution of the dissolvent liquid and the soluble material.

The inlet-conduit or pipe 0 for the di. solvent liquid usually discharges into the up per end of tl1e shell A and preferably extends ongitudinally within said shell for a con-sid erable distance. Said conduit or pipe C may be held in osition by any suitable support (Y and may heating fluid by a conduit or pipe C The dissolvent liquid supplied by the conduit or pipe t3 feeds through the shell A in a direction opposite to that of the soluble material disc iarged into said shell by the inlet-conduit or pipe B. Said dissolvent liquid preferably overflows from the uppermost compartment (1 to which it is supplied and feeds by gravity to the next lower compartment a, and continucs its downward passage from one compartment to another, until it escapes from 'the lower end oi the shell A into the chamber D. It is. obvious, however, that the conveyer-blade a may be perforated to permit the passage of the dissolvent liquid theree supplied with steamer other through, and in that event, the shell forreceiving said liquid and the soluble material may be. arranged in a substantially horizontal The revoluble movement oi the shell A may be eiiected by any suitable actuating -the shell A is preferably reduced to a minimum by suitable rollers A which support said shell. These rollers engage projecting tires A upon the shell A and are preferably mounted upon the upper and lower ends of rock-arms A A which are usually arranged on opposite sides of a vertical plane rejected through the axis of the shell A. mediate portions of the rock-arms are pivoted or journaled in supports A which are ill adjustable towards and away from each other by suitable bolts A and are held in position by suitable fastening means A.

The undissolved material fed upwardly by the conveyer-blade a is discharged into a suitable rece tacle or chamber whence it may be removed liy any desirable means. In the preferable construction of my invention, said material is discharged into the lower end of an inclined cylindrical receptacle or chamber E which usually projects within the upper end of the shell A and revolves therewith. A portion of the'inclos'ing wall of the receptacle or chamber E is generally erforated for permitting the escape into tlle shell A of any liquid and small particles of undissolved material admitted to said receptacle or chamber. The undissolved material discharged into the receptacle or chamber E and not escaping through the perforations in its inclosing wall is fed upwardly through said receptacleor chamber by any suitable feeding means, as a spiral conveyor-blade e, and is discharged from the upper end of the receptacle or chamber E to the exterior of the shell Al The inlctc'ond.uit or pipe {1 preferably extends longitudinally witlnn the receptacle or chamber l) and discharges the strong or fresh dissolvcnt liquid upon the undissolved material, and the perforations in said receptacle or chamber permit the ready escape of said strong or fresh dissolvent liquid into the inclosing shell A, whence it passes from one compartment to another in a direction opposite to that of the n'iatcrial fed by the conve ;.'erblmlc (1. The dissolvcnt liquid esca lug from the receptacle or chamber E faci itates the outward passage of small particles of undissolved material through the perforations in the inclosing wall of said receptacle or chamber, and said particles are fed downwardly towards the conduit or pipe B by a suitable spiral conveyer-blade a which is usually arranged within the upper end of the'shell A at the exterior of the receptacle or chamber 1) and is nclined in a dirc lion opposite to that of the conwyvrl lade (1..

Any suitable means may be used for l'c -ding the undissolved iualcrial from the inclosing slicli A into the chamber or receptacle E, and l have illustrated for such purhe interpose, a feeding chamber F, a pocket or scoop f,-and an o emng e in the receptacle or chamber E. T e feeding chamber F usually encircles the lower or inner end of the receptacle or chamber E and is inclosed between adjacent ortions of the inner face of the shell A, tie periphery of the rece tacle or chainber E and substantially para el circular shoulders or flan es f f 2 interposed between said faces. 'lhe shoulders or flanges f f are formed with openings f which facilitate the onward passage of the dissolvent liquid through the chamber E, and additional openin s f v 5 with which the advance ends of t e conveyer-blades a a are alined for feeding the undissolved material through said openings into the chamber F. The pocket or scoop f extends transversely between the shoulders or flanges f f and projects forwardly from. the rear edge of the opening 0 towards the inner face of the s iell A; This pocket or scoo serves to receive and hold the material fe( to-the chamber F, and as said pocket or scoop is elevated, the material therein falls-downwardly by gravity into the receptacle or chamber E.

The feedin chamber F, the pocket or scoop f, and t e o enin e in the revoluble receptacle or cham er l form a particularly simple and efficient means for feeding the undissolved material from the shell A to said revoluble receptacle or chamber E. My im- )l'OVfid lixiviating apparatus may, however, be provided with a stationary rece tacle or chamber for receiving the undisso ved material and in that event, a did'erent means for feeding the undissolved material into said receptacle or chambecwould be rcquired. buch a modified construction of my invention is illustrated in Fig. 7, in which A represents the iuclosing shell for receiving the dissolvcnt liquid and the soluble material, B a stationary receptacle or chamher for receiving the undissolved. material, and B an additional rccc )taclc or chamber for receiving the matcrial dischar ed from the first receptacle or chamber whic i preferably consists of a chute. The undissolved material is usually fed into the first receptacle or chamber 3 by one or more rotary pockets a which are formed with open in ner portions or ends and are secured to the inner face of the shell A within a feeding chamber a provided at the u per end of said shell A Suitable s irzl conveyerblades a feed the material tirough the shell A into the sides of the pockets a, and when said pockets are elevated above the receptacle or chamber 13 the material therein feeds by gravityfrom their open inner poi-lions or ends into said receptacle or chamber. The second receptacle or chambcr'B preferably consists of a perforated rcvolublc cylinder provided with a conveyorbladc If which discharges the material from teams the. outer end of said receptacle or chamber. It is obvious, however t at the receptacle or chamber B may conduct the material to an suitable feeding means, as an endless be t provided with buckets or pockets for I receiving said material.

As the .material is passing through the receptacle or chamber E, the inlet-conduit or pipe C discharges the strong or fresh dissolvent material thereon for preventing the escape of any soluble material, and. said liquid, together with any additional liquid mixed with the undissolvod material and small particles of said material, escape throu h the perforations of said rcceptacle or c iamber into the inclosing shell A and then pass. into the feeding chamber F through the openings in the upper side The liquid fed through the upper side of the feeding cham- [reference to the f .u'egoiug description and siderable n ber continues its onward movement towards the chamber D, and the undissolvcd material fed through said siile of the chamber l is hg'ain returned to the receptacle or chamber E.
